Wicket 1.5 - Generic JSON Response
I've been working on various implementations of this all day, to try and
output a simple JSON response, as Content-Type: application/json, with
absolutely no luck. My current class is setup as below. However, when
sending a request to the "Feed" URL, it comes back as text/plain, with the
JSON formatted string embedded below. What am I doing wrong? Thanks.
-----------------
public class Feed extends WebPage implements IMarkupResourceStreamProvider {
private static final long serialVersionUID = 1L;
@Override
protected void configureResponse(WebResponse response) {
super.configureResponse(response);
response.setContentType("application/json");
response.addHeader("Content-Type", "application/json");
}
@Override
public void renderPage() {
getResponse().write("[{'id':111,'title':'MainEvent','start':'2012-04-10T07:00:00','end':'2012-04-10T09:30:00','url':'?EventID=111','allDay':false}]");
}
public IResourceStream getMarkupResourceStream(MarkupContainer container,
Class<?> containerClass) {
return new StringResourceStream("");
}
}

If you have a number of JSON end-points, the best architecture would
probably be to use Spring MVC to do the JSON handling, and then map the
Spring MVC paths into your web app using the Wicket filter ignore paths
option (
https://cwiki.apache.org/WICKET/best-practices-and-gotchas.html#BestPracticesandGotchas-
).
Thanks

There is no code in Wicket that will check for this annotation in
non-Component classes.

Any suggestions on how I might roll my own? I tried a few things like
injecting the Feed class and annotating it, but I suspect it's too late at
that point.

IAuthorizationStrategy is not used for IResource at the moment.
You need to roll something yours for this check.

Is there any way to tie this to the standard wicket security model? Right
now, our web pages are all annotated with @AuthorizeInstantiation("admin"),
so how would we be able to apply it to this scenario?

Thanks Martin! For everyone else's reference, the final code that is
working looks like this:
--------------Feed.class----------------
public class Feed extends AbstractResource {
private static final long serialVersionUID = 1L;
protected ResourceResponse newResourceResponse(Attributes a) {
ResourceResponse r = new ResourceResponse();
r.setContentType("application/json");
r.setWriteCallback(new WriteCallback() {
public void writeData(Attributes a) {
a.getResponse().write("[{\"id\":111,\"title\":\"MainEvent\",\"start\":\"2012-04-10T07:00:00\",\"end\":\"2012-04-10T09:30:00\",\"url\":\"?EventID=111\",\"allDay\":false}]");
}
});
return r;
}
}
-----------End Feed.class--------------
--------------Application.class----------------
@Override
protected void init() {
super.init();
mountResource("/Feed", new FeedReference());
}
public class FeedReference extends ResourceReference {
public FeedReference() {
super(FeedReference.class, "feed");
}
public IResource getResource() { return new Feed(); }
}
-----------End Application.class-------------

Thanks for the tip, that definitely sounds like the way to go. Quick
follow-up, how does one mount an AbstractResource within the application.
There doesn't appear to be an Abstract reference class to instantiate using
something like:
mountResource("/Feed2", new ResourceReference(Feed2.class));
Thanks again!

Hi, Ahijah. I think you should use a resource for this, not a page.
Something like:
class MyResource extends AbstractResource {
ResourceResponse newResourceResponse(Attributes a) {
ResourceResponse r = new ResourceResponse();
r.setContentType("application/json");
r.setWriteCallback(new WriteCallback() {
public void writeData(Attributes a) {
a.getResponse().write("your json here"); }
});
return r;
}
}
